The invention relates to a high-pressure high-power hydraulic servo ejection system. The invention aims to provide a high-pressure high-power hydraulic servo ejection system which comprises ejection hydraulic loops and a pulley speed-increasing walking mechanism, a variable load is accelerated to 20m/s and 45m/s in a short stroke in a hydraulic and mechanical combined hybrid ejection mode, two hydraulic loops are designed for the variable load, an energy accumulator station is instantly released, hydraulic oil enters a hydraulic cylinder through a servo valve to achieve the instant acceleration of the load, the double-loop design can be switched according to the flow requirement, a large-flow two-way valve and a servo valve are used in parallel to satisfy the large-flow and high-frequency response control requirement, and the technical problem that the flow supply of the high-frequency response servo valve is insufficient is solved. The inflation pressure of each energy accumulator in the energy accumulator station is distributed in a stepped mode, the problem that one system develops various working pressures is solved, and the device has the advantages of being compact in structure, high in working efficiency, good in reliability and the like and has important significance on the development of a high-performance ejection system.
